JACOB LEVY, OF NEW YORK, N. Y., ASSIGNOR TO THE LEE IMPROVEMENT COMPANY, OF NEW YORK, N. Y., A CORPORATION 01* NEW YORK.

STRAINER.

Application filed July 22,

To all whom it may concern:

Be it known that I, JACOB LEVY, a citizen of the United States, and a resident of the city of New York, in the county of New York and State of New York, United States of America, have invented certain new and useful Improvements in Strainers, of which the following is a specification.

My invention relates to strainers such as are used in conjunction with roof leaders or vent pipes, and its object is to improve upon devices of this class and to provide a wire basket strainer of simple construct-ion which may be readily affixed to the end of a pipe by a novel arrangement which I have invented.

To these ends my invention resides in the construction and arrangement of parts described in the following specification, the novel features whereof are set forth in appended claims.

Referring to the drawings, Figure 1 is a sectional side elevation of the upper end of a pipe with my improved strainer attached thereto. Fig. 2 is a sectional plan view of some of the parts shown in Fig. 1, the section being taken on the line 2 2 of the latter figure. Fig. 3 is a sectional side cleva tion of the pipe to which the strainer is to be atlixed, and the lower end of the strainer showing my novel fastening arrangement and the manner in which it is used.

Like characters of reference designate corresponding parts in all of the figures.

designates the upper end of a roof leader or other structure in conjunction with which it is desired to use a strainer.

11 is the strainer which may be made in many forms and by different constructions. For example, it may be made in the shape and in the manner shown in Fig. 1, in which 12 designates a circular wire hoop around which the ends of a plurality of wires 13 are bent. These wires are then carried down in such a way as to form a basket with its upper portion cone-shaped. They are then bent over a second wire hoop 14 to which they are fastened by means of a binding wire 15. 16 is a third circular wire hoop through which the wires 13 pass. These may be bent to engage with the hoop 16 in the manner shown, or, it desired, may be fastened thereto in some such manner as they are fastened to the hoop 14.

From the hoop 16 the wires Specification of Letters Patent.

extend downward in practically cylindrical form and are each permanently allixed to a split band 17.

20 and 21 designate a pair of lovers which are connected by means of brackets 22 and 23 to the band 17 at diametrically opposite points. 2-11 is a similar lever connected to the band 17 at a point midway between the brackets 2 and 23 by a similar bracket 25. 26 and 727 are other levers connected by brackets with the two ends of the split band 17. The levers 20 and 21 are slidably connected together near their inner ends by means of a rivet 28. 29 designates a similar rivet cormccting together the lovers 24, 26 and 27.

In Figs. 1 and 3 it may be seen that the levers '36 and 27 are provided with slots through which the pin or rivet 29 may slide. 30 designates a washer which is placed between the levers 24; and 26. This washer is for a purpose which will fully appear hereinafter. It may be seen that the brackets which fasten these levers to the inner surface of the split band may be carried down under the lower edges of the levers into such a position as to limit the downward movement of the levers. Or, if desired, one of each pair of levers may be constructed as shown at 27 to accomplish this purpose.

Now,when it is desired to allix the strainer above described to the end of a pipe or other object, the cylindrical-shaped portion of the strainer is thrust within the pipe with the levers bent upward into the position in which they are shown in Fig. 3. The levers 20 andv 21 are then pushed down until they are in horizontal alinement, which will, of course, produce a toggle-joint leverage which will press the split band 17 outward against the inner surface of the pipe. The levers 2 1, 26 and 27 are then pressed downward until they are all in horizontal alinement, which movement will again expand the split band and cause it to be pressed outward against the inner surface of the pipe 10.

The parts above described, with the exception of the washer 30, are preferably constructed of some non-rustable material such, for example, as galvanized iron. The washer 30, however, is of iron not galvanized, so that as soon as it is exposed to moisture it will become oxidized and will rust in place, thus locking the levers together. As the levers 20 and 21 are below levers 2a, 26 and 27, these too will be locked in position by the rusting ol' the washer 80.

It is evident that if desired, washers similar to that designated by the numeral 30, lnay be placed between the levers and 21, and also similar rustable levers maybe placed between each of the levers and the bracket which connects it with the split band 17. This arrangement provides a strainer which may be permanently itfl'lXGCl in a moment and without the use of tools to the end of a pipe or other similar desired opening. It e'l'lectively does away with the necessity of cutting or tapping the pipe and with the use of solder. It is cheap to manufacture and simple to use.

The fastening device wnich l have shown herein may, of course, be used in conjunction with other forms of strainers and with other devices than that which I have selected to illustrate its use.

hat 1 Claim is 1. A strainer comprising a split annular band adapted to fit within a circular body to which the strainer is to be attached, and meansl'or expanding said band within the body and for iorming a rust-joint to permanently hold the band within said body.

2. A strainer comprising a split annular band adapted to fit within a circular body to which the strainer is to be attached, a lever arranged to expand and hold said band within the body, and means for forming a rustjoint for locking said lever in place.

3. A strainer comprising a split annular band adapted to fit within a circular body to which the strainer is to be attached, a pair of toggle levers connected with saidband within the body, and means for forming a rust-joint to hold said levers in place.

4. A strainer comprising a split annular band adapted to fit within a circular body to which the strainer is to be attached, a pair oi toggle levers connected with said band and to each other and arranged to expand and hold the band within the body, and means for forming rust-joints at the connections of said levers for holding said levers in place.

5. In combination with a pipe, a strainer comprising a split band adapted to fit Within said pipe, a plurality of levers pivotally connected with said band and with one another, said levers being arranged to expand and hold the band within the pipe, and a rustable washer at one of said lever connections arranged to form a rust-joint at said connection and hold the levers in place.

6. In combination with a circular pipe, a wire strainer comprising a split annular band adapted to fit within said pipe, a plurality of toggle levers pivotally connected to the inside of said band and with one another, said toggle levers being arranged to expand and hold the band within the pipe, and rustable washers at said lever connections arranged to form rust-joints at said connections to hold them in place.

in testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
